Chronic compression or ischemia of the spinal cord in the cervical spine causes a clinical syndrome known as cervical myelopathy. Recently, a new term "degenerative cervical myelopathy (DCM)" was introduced. DCM encompasses spondylosis, intervertebral disk herniation, facet arthrosis, ligamentous hypertrophy, calcification, and ossification. The pathophysiology of DCM includes structural and functional abnormalities of the spinal cord caused by static and dynamic factors. In nonoperative patient

STUDY DESIGN: A nationwide population-based study. PURPOSE: Osteoporotic vertebral compression fracture (OVCF) is a major public health issue. This study examined the incidence and management trends of OVCF in South Korea. OVERVIEW OF LITERATURE: The incidence rates, management trends, and patterns of OVCF differ in different parts of the world. The age-standardized OVCF incidence rate in 2015 was higher in the United States and Asia than in Europe. METHODS: A nationwide database (2012-2016) acq

STUDY DESIGN: Population-based study. From 2008 to 2017, data from the national database of the Korean Health Insurance Review & Assessment Service were analyzed. The national insurance system and all medical expense bill data of the entire population are included in the database. OBJECTIVE: The aim of this study was to elucidate the incidence and management trends of metastatic spinal tumors in South Korea. SUMMARY OF BACKGROUND DATA: The spine is the most common location of bone metastases. Ho

The incidence of infectious spondylodiscitis (IS) has increased in recent years due to an increase in the numbers of older patients with chronic diseases, as well as patients with immunocompromise, steroid use, drug abuse, invasive spinal procedures, and spinal surgeries. However, research focusing on IS in the general population is lacking. This study investigated the incidence and treatment trends of IS in South Korea using data obtained from the Health Insurance Review and Assessment Service.

ABSTRACT: Despite the increasing prevalence of spinal surgery in super-elderly (SE) patients, the outcomes and complication rates have not been fully elucidated. The purpose of this study was to compare the outcomes and complications of lumbar spinal fusion for degenerative lumbar spinal stenosis (DLSS) in SE patients aged 80 years and over with those in patients aged 65 years and over, and under 80 years.This study analyzed 160 patients who underwent spinal fusion for DLSS between January 2011

Titanium mesh cage filled with the autogenous cancellous bone shortened operation time and reduced the risk of complications in the donor site compared with the group that used the tricortical iliac bone.

BACKGROUND: We sought to evaluate the long-term outcomes of long-level instrumented posterolateral fusion (PLF) directly compared to those with short level instrumented PLF for degenerative spinal stenosis. METHODS: From 1987-2002, patients who underwent instrumented PLF with wide decompression for degenerative spinal stenosis were reviewed. A total of 295 patients were available for follow-up over 10 years (mean, 14 years). These patients were divided into Group 1 (fusion of 1 or 2 levels) and

STUDY DESIGN: Retrospective comparative study. OBJECTIVE: To investigate the radiographic and clinical effectiveness of surgical treatment using a posterior-only approach, as compared with a combined antero-posterior approach, in patients with infective spondylodiscitis. SUMMARY OF BACKGROUND DATA: Spondylodiscitis is the most common infectious disease of the spine. There is currently no consensus over the surgical approach, use of bone graft, and type of instrumentation for optimal treatment of

BACKGROUND: Osteoporosis and osteoporotic fractures are widely known as complications of rheumatoid arthritis. Kyphoplasty (KP) is known as an effective treatment modality for reducing pain and correcting kyphotic deformity in osteoporotic vertebral compression fracture (OVCF). However, cutcomes of KP in rheumatoid patients are not well known. The purpose of the study was to investigate the clinical and radiological outcomes of balloon KP on OVCF in patients with rheumatoid arthritis. METHODS: A
